  • Inexpensive, easy-to-use fixed-point maintenance apparatus

    • One week plateau duration
    • No hassle automatic realizations
    • Used daily in our Primary Lab

    The gallium melting point (29.7646 °C) is a critical temperature. Thermometers used in life science, environmental monitoring, and many other applications depend on it for accurate calibrations. Lab standards rely on it as an ITS-90 check standard and as a means of measuring drift between calibrations. Fluke Calibration now makes it easy to use.

The new 9230 Gallium Maintenance System works with Fluke Calibration's Model 5943 Stainless Steel Gallium Cell to provide melting plateaus that last a week, with results approaching what can be achieved in a Fluke Calibration maintenance bath. Not a day. Not a day-and-a-half. One week.

The Model 5943 Stainless Steel Gallium Cell holds a gallium sample that is 99.99999+ % pure. The gallium is sealed in a PTFE envelope in a high purity argon atmosphere, which is itself sealed inside a stainless steel housing. This double-sealing method reduces leaching into the gallium sample and ensures a life of ten years or longer for the cell.
